Combination of flyovers, subways and ramps along 6.5-km stretch to relieve traffic congestion
The proposal to create a traffic corridor connecting Anna Salai and Poonamallee High Road through the congested neighbourhoods of Chetpet, Nungambakkam and T. Nagar is gaining momentum.
It was a decade ago Chennai Metropolitan Development Authority (CMDA) came up with the idea of a 6.5-km stretch connecting the two arterial stretches.Two-part solution
The Corporation modified the original alignment to create two corridors — a 3.5-km stretch from Anna Salai to Mahalingapuram and a 3-km flyover connecting Thirumalai Pillai Road and Poonamallee High Road.
“The 3-km elevated stretch connecting Poonamallee High Road and Thirumalai Pillai Road will cover five traffic bottlenecks including Chetpet junction, Sterling Road junction, Tank Bund Road junction and Valluvar Kottam High Road. There will also be additional ramps on stretches such as College Road,” said an official of the Chennai Corporation.Public consultation this month
After a public consultation, to be held this month, the design will be selected.
For the 3.5-km stretch, the feasibility report is ready and public consultation has been completed. The consultant has provided nine options for easing traffic congestion on this stretch.Land acquisition may be avoided
Ramps will be redesigned and made seven metres wide to facilitate construction without land acquisition on the 3.5-km stretch.
Tamil Nadu Urban Infrastructure Financial Services Limited has completed feasibility study for the 3-km flyover at a cost of Rs. 90 lakh. The civic body is likely to avoid land acquisition for the facility.
The consultant has proposed more than 10 higher-order traffic solutions to ease congestion on the stretch between Ega Theatre on Poonamallee High Road and Thirumalai Pillai Road in T. Nagar.Arterial stretches
According to feasibility studies, a chunk of vehicles plying on these stretches had T. Nagar, Nungambakkam, Egmore or Chetpet as their places of destination or origin. Junction improvement and pedestrian subways are likely to be important components in the creation of the corridor.
